Out-of-Season Storage
WARNING
As a safety precaution, when boat is in storage, remove positive (+) battery cable.
This will eliminate possibility of accidental starting of engine and resultant over-
heating and damage to engine from lack of water.
In preparing for out-of-season storage, two precautions must be considered: 1) The engine
must be protected from physical damage caused by freezing trapped water and 2) the en-
gine must be protected from rust, corrosion and dirt.
If the length of storage time between each use varies from 1 week to 2 months, it is recom-
mended to add Fuel System Treatment and Stabilizer to the fuel tank regularly each time
gasoline is added following the recommended amount as described on the Fuel Stabilizer
container.
The following storage procedures should be followed to prepare the Jet Drive for out-of-sea-
son storage or prolonged storage (two months or longer).
CAUTION
Never start or run the Jet Drive without water circulating through the cooling sys-
tem to prevent damage to the unit.
Fuel System
IMPORTANT: Gasoline containing alcohol (ethanol or methanol) can cause a forma-
tion of acid during storage and can damage the fuel system. If the gasoline being
used contains alcohol, it is advisable to drain as much of the remaining gasoline as
possible from the fuel tank, remote fuel line, and engine fuel system.
The most effective method for storage preparation is to add the recommended amount of
Fuel System Treatment and Stabilizer and Quickleen products as described on their con-
tainers to the fuel tank before the last operation of the boat. Adding Fuel System Treatment
and Stabilizer will help prevent the formation of varnish and gum in the gasoline. The Quick-
leen product will help clean and lubricate the fuel injectors.
To properly prepare the engine for prolong storage:
a. Drain the fuel from the Vapor Separator Tank (VST) into a suitable container by re-
moving the drain plug. After the fuel has been drained, reinstall the drain plug.
b. Remove the water separator fuel filter and empty the fuel into a suitable container.
Discard both the fuel and the filter properly.
c. Premix the following in a container:
(1.)0.68 oz (20 cc) or 2 tablespoons of Premium Plus Outboard oil or 2-Cycle Out-
board Oil.
(2.)0.27 oz (8 cc) or 2 teaspoons of Quickleen lubricant.
(3.)0.27 oz (8 cc) or 2 teaspoons of Fuel System Treatment and Stabilizer.
d. Pour this mixture in the new water separator fuel filter.
e. Reinstall the filter.
f. Prime the fuel system as outlined in the STARTING PROCEDURES.
g. Using a flushing attachment, start the engine and allow the engine to run at idle
speeds for 3 minutes.
